6. Carrying device according to one of claims 1 column is inextricably attached, while the other to 5, characterized in that the retaining ring by means of a hollow cylinder formed by it (18, 38) has slots, which with the limiters pillar-side ends of the footrests and the ting surfaces of the recesses (16, 36) to 60 with the column fixed retaining ring, reaching through work together. and can be screwed into the end of the column from below

7. Carrying device according to one of claims 1 screw bolt is axially secured. At this known to6, characterized in that the limited construction is located directly in the screwing surfaces the recesses (16,36) slots connection itself via the long lever arms of the (16 (7), which with the retaining ring (18, 38) 65 footrests through the received by these cooperate. Support reaction forces generate a considerable amount of torque that gradually eases the

Screw connection causes. The manufacture of the

Individual parts, especially the hollow cylinder segments, are expensive. Here, too, assembly is carried out with the help of the Screw connection cumbersome and time consuming.

The object of the invention is to create a support device of the type mentioned, which from particularly simply designed and thus cheap to manufacture items, easily and quickly mount is not overstrained at any point by the forces and moments to be transmitted and does not gradually loosen at its junctions under the action of force. In particular the new support device should not contain any screw connections.

This object is achieved by a support device of the type mentioned at the beginning, which is characterized according to the invention in that for support of the footrests against the outside wind of the S; h: le the entire frontal area of the footrest ! le.v-.iien is that furthermore the recesses in one lauv.en are arranged from the column-side ends of the footrests and that the Halleiiüg with its edge surface facing the column force-:;: hiüssig on the column-side boundary surface of the Recesses.

The new carrying device has only a few, also extremely simply designed individual parts and has no screw connections. The assembly is quick and easy with one: Minimum of work. The force distribution is favorable at all points of the device and does not show any overstrained Set up. In addition, there is a clamping effect of the upper areas on the column side Ends of the footrests on the column surface under the action of a vertical, downwardly directed Force on the pillar loosening the connection

radially directed force F applies. The torque M is compensated for by the reaction force N , which is a result of the surface contact mentioned and is distributed over the end faces of the footrests 14 on the column side.

The number of footrests 14 can be smaller or larger than four. Your radial location will be in suitably determined, for example by slots in the retaining ring 18 that correspond to the slots 16α in the boundary surfaces of the recesses ίο 16 work together. This results in a downward stripping of the retaining ring and a shift the footrests 14 prevented from their radial position, and there is a mutual guide engagement between footrests and retaining ring.

In the F i g. 3 to 7 show a modified embodiment of the carrying device according to the invention, which has a particularly decorative appearance and is easy to manufacture. The lower end of the column 32 is designed here as a conical surface 40 with the cone angle ψ . The retaining ring 38 has sections in the areas between the footrests 34 which extend to the conical surface 40 of the column 32 and the ends of which have inclined end faces 42, the inclination angle of the end faces 42 corresponding to the angle ff of the conical surface. The retaining ring 38 is slightly curved to form a convex top. The footrests 34 are made of bent sheet metal and have a U-shaped cross section (FIG. 6). At their outer ends they have plastic feet 37 fastened in a suitable manner.

Figures 8 and 9 show the assembled support 30 of this embodiment. Of the The inner edge of the retaining ring 38, which forms the end faces 42, is formed by recesses 44 that are set back interrupted, the short, protruding in the direction of the center of the halter ring 38 Tongues 46 are limited (Figs. 5, 8 and 9). The recesses 36 are in the opposite legs of the footrests 34 with a U-shape Cross-section arranged. The short tongues 46 of the retaining ring 38 engage in the space between the opposite legs of the footrests 34 a.

On both sides of the tongues 46 in the radially outer corners of the recesses 44, narrow stop surfaces 48 are provided, the width t of which corresponds to the sheet metal thickness of the footrests 34. As can be seen in particular from the left-hand part of FIG. 8 and 9, all footrests 34 are hooked onto the retaining ring 38 in such a way that their inner lower parts 51 protrude through the recesses 44 in the retaining ring 38 downwards. The edge 50 of the recesses 36 on each side of the footrests 34 (FIG. 6) lies against the narrow stop surface 48 of the retaining ring, while the outer edge of the retaining ring 38 lies in the corner 52 of the recess 36. The corner 52 is arranged opposite the edge 50 (FIG. 6 and left side of FIG. 8). The tongues 46 make it easier to hook and guide the inner sides of the footrests 34 in the retaining ring 38. One side of the recess 36 protrudes slightly inward below the corner 52 in order to prevent the retaining ring 38 from moving downward as a protruding hump 53.

After hanging the footrests 34 in the retaining ring 38, the column 32 is between the ends the footrests moved downwards and the conical surface 40 securely into that formed by the end faces 42 conical opening of the retaining ring 38 driven. The column-side ends of the footrests 34, which are adapted to the circumference of the column 32 with rounded surfaces are slightly oversized, so that when the column 32 is pushed into the retaining ring 38, a wedge effect between the retaining ring and Column emerges. This results in a particularly stable and secure connection that is attached to the column 32 transfers acting load safely and without overstressing on the footrests 34.

The in the F i g. 1 and 2 illustrated embodiment of the present device can also have the conical and end faces 40 and 42: this is achieved by the fact that the supports 20 and 22 replaced by a conical surface at the end of the column 12 and corresponding conical surfaces at the bottom Provides column-side end faces of the footrests 14, as shown with dashed lines 41 is. The stop 24 can then be omitted.

In addition to the advantages of the carrying device according to the invention already explained, such as fast and simple assembly of the individual parts with very good stability and load-bearing capacity of the finished support device, as well as easy and cost-saving production possibility of the simply shaped components the further advantage that the individual parts of the support device do not require any finishing, but rather can be used as they come from the casting or pressing device. Only surface treatment may be required. Here is the carrying device not limited to furniture feet.
